Actual results could differ significantly from these estimates. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     In management’s opinion, the accompanying unaudited condensed consolidated financial statements contain all normal recurring adjustments necessary to state fairly the financial information included herein.

This guidance requires vendors to develop the best estimate of selling price for each deliverable and allocate the arrangement consideration using this selling price. This guidance also expands the disclosure requirements to include both quantitative and qualitative information. This guidance is effective for fiscal years beginning after June 15, 2010. The Company is currently evaluating the impact of the adoption of this guidance on its results of operations and financial position. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     In October 2009, the FASB issued guidance to clarify that tangible products containing software components and non-software components that function together to deliver a product’s essential functionality will be considered non-software deliverables and will be scoped out of the software revenue recognition guidance. This guidance is effective for the fiscal years beginning after June 15, 2010.

The determination of whether a company is required to consolidate an entity is based on, among other things, an entity’s purpose and design and a company’s ability to direct the activities of the entity that most significantly impact the entity’s economic performance. This guidance requires ongoing reassessments of whether an enterprise is the primary beneficiary of the variable interest entity. This guidance is effective for fiscal years beginning after November 15, 2009. The Company adopted this guidance in the first quarter of 2010. The adoption did not impact the Company’s results of operations or financial position. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     In January 2010, the FASB issued guidance that expands the interim and annual disclosure requirements of fair value measurements, including information about the movement of assets between levels 1 and 2 of the three-tier fair value hierarchy established under fair value measurement guidance. Separate disclosure is required for purchases, sales, issuances and settlements in the reconciliation for fair value measurements for level 3 assets. Except for the detailed disclosure in the level 3 reconciliation, which is effective for fiscal years beginning after December 15, 2010, all the other disclosures under this guidance are effective for fiscal years beginning after December 15, 2009. The Company adopted this guidance in the first quarter of 2010. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif"> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock Description containing the entire organization, consolidation and basis of presentation of financial statements disclosure.
